IMPROVEMENT IN SHIF TING BACKS FOR VEHICLE-SEATS.

Specification forming part of Letters Patent No. 147,950, dated February 24, 1874 application filed January 2, 1874.

To all whom it may concern:

Be it known that I, JOHN M. LANDIS, of East Lampeter township, in the county of Lancaster, (address Fertility P. 0.,) State of Pennsylvania, have invented an Improvement in Shifting Tops on Vehicles, of which the following is a specification:

This invention relates to a class the object of which is to convert a top buggy or vehicle into what are termed trotting buggies or vehicles by making the top with the side rails detachable, for which various devices are employed, often complicated, and with projecting appliances to the seat, found to be unsightly, or in the way when used without the top. To obviate these objections, I employ very simple means, and which are found highly efficient, the base-plate or headrail being made in two parts, each turned up behind to form a brace and support for the lazy-back or back rail.

The accompanying drawings illustrate my invention, in which Figure 1 shows the lazy-back and supports detached from the seat, to which back the top is attached in the ordinary manner, hence not shown. Fig. 2 shows the seat when the top is removed. The dotted lines show the lugs or ears G, perforated for a binding-screw, I, to match with the screw-thread out into the iron bands H, connected with the seat, showing six points of attachment by means of said screws.

A very brief explanation will enable any one skilled in the art to make and use my invention.

The seat A, Fig. 2, is like an ordinary seat, with six iron bands, H, let flush into the wood of the three raised sides h h h of the same. The upper edge of these sides is fiat. The straps are perforated centrally on the flat or upper face of said sides, with a screw-thread cut therein. Thereby the seat is left smooth and not encumbered with projecting portions, so liable to catch into the clothing or mar the appearance of the seat when used as a trottingbuggy. The top is attached in the ordinary manner at F, and the supporting-arm E, with nuts f, to the base-iron D on each side of the seat. In addition to F andE, these base-irons D are provided with projecting perforated lugs G at three points. The side or arm irons c are affixed, by rivet or otherwise, ate, to the baseiron I), and severally curved upward and attached to B, to form the lazy-back of the seat, as shown by Fig. 1. Thus the top of the buggy is connected to these combined irons and lazy back, and jointly attached to the upper raised sides h of the'seat, by means of the said perforated lugs G, thumb or binding screws I and seat-plates H. The dotted lines indicate their relative position or points of contactwhen in place.

I am not aware that the base-plate provided with perforated lugs, and combined with the arm or side plate and back rest or board, was ever so made or used. I am aware that the removal of the six thumb-screws may be deemed less convenient; but when we consider that they can be removed or inserted in less than one minute, and the advantages resulting from the security of the attachment, and the neatness of the seat when detached, the simplicity and cheapness and durability present features that will am plycompensate for a slight loss of time, should such happen to be the case, which, all things considered, is questionable. Therefore,

WVhat I claim as my invention is The baseplates D D, with top supports E F and perforated lugs G, turned up from the seat behind, to form a brace on each side for the back rail B, in combination with the side rails c, all constructed and attached to the seat in the manner and for the purpose set forth.

JOHN M. LANDIS.
